Abstract
An antifuse detection circuit is described which uses a latching circuit and two antifuses. The antifuses are coupled between the latch circuit and ground. The latching circuit described is a differential circuit which can detect which one of the two antifuses has been programmed. The circuit accurately detects an antifuse which has a relatively high resistance after being programmed.
